So the only exception is the one reported by tob. These are the bits
I've collected:

Yan's S10-3t: model: 1, fw: 7.4, id: 0x1e0b1, caps: 0xd04771/0xa40000/0x4a0500 (2 button clickpad)
tob's S10-3t: model: 1, fw: 7.4, id: 0x1e0b1, caps: 0xd04771/0xe40000/0x5a0400 (?)
hp Envy 14/mini210:
              model: 1, fw: 7.4, id: 0x1e0b1, caps: 0xd04771/0xe40000/0x5a0400 (1 button clickpad)

I asked tob to double-check his model and whether his touchpad emits
BTN_MIDDLE or not but get no reply yet. I've checked 4 S10-3t
purchased at different dates and all of them show same exc0 cap, but I
have to say other models selling in other parts of the world may be
still different.
